ubuntu 9.10 hanging when no monitor connected

[Ralph Hoflich]

I have an on-board graphics card and a PCI graphics card. When I don't connect a monitor to the new ubuntu 9.10 on-board graphics card, the system hangs and doesn't boot. Connecting a monitor to it starts up the system, but it should be able to boot headless.

Hi Ralph,

The warning reported here typically indicates that it took longer for your system to resume from suspend than expected. I believe there is a 5 sec barrier which your system likely exceeded. Typically you'll see something similar to "PM: resume devices took 8.664 seconds" in your dmesg output when this happens. A patch to prevent this warning has been applied via bug 464552. As a result I'm marking this as a duplicate to bug 464552. Please continue to track this issue at that report. Thanks!

Confirm this on lucid too. I don't think the log show the info about the problem reported here, because the system just can't boot without a monitor connected to it.

Someone reported there are workaround @ http://ubuntuforums.org/showthread.php?t=1292212&page=2

But I have tried those all, none works for me.
